目的探讨N末端B型利钠肽原(NT-proBNP)“双截点”策略分析在急性呼吸困难鉴别诊断中的价值.方法按照“排除”截点和“诊断”截点并依据年龄分层把我院以急性呼吸困难入院的139名患者分成9组,分析最后诊断结果与NT-proBNP水平的关系及最初诊断与最终诊断之间的差别情况.结果 NT-大学孙逸仙纪念医院急诊科proBNP水平处于“排除”截点以下和“诊断”截点以上的患者急性心力衰竭的诊断准确率高.而处于“灰区”的患者有合并心力衰竭的存在,尤其是年龄＞ 75岁的患者；对于“灰区”尤其是年轻患者更易误诊为心力衰竭.结论 NT-proBNP“双截点”策略分析对急性心力衰竭有重要的诊断价值,尤其是依据年龄分层后NT-proBNP处于“排除”截点以下和“诊断”截点以上的患者的诊断意义很大.

Objective To explore the value of strategy analysis on ‘double cutting points’ of NT-proBNP for the differential diagnosis of acute dyspnea.Methods 139 patients with acute dyspnoea were divided into 9 groupes according to ‘elimination’ and ‘diagnosis’ of the cutting points of NT-proBNP and to age stratification.The association of the final diagnostic results and the levels of NT-proBNP and the difference between the initial diagnosis and the final diagnosis were analyzed.Results Patients with a NT-proBNP level between ‘elimination’ and ‘diagnosis’ of the cutting points had a higher accuracy rate of diagnosis for acute cardiac failure.Patients with a NT-proBNP level in the ‘grey area’ had a higher possibility of acute cardiac failure,especially for those older than 75.Conclusions Strategy analysis on ‘double cutting points' of NT-proBNP has a great value in the diagnosis of acute cardiac failure,especially for the patients with a NT-proBNP level between ‘elimination’ and ‘diagnosis’ of the cutting points.
